What was found
OWNER COMPLAINED OF STARTER BENDIX HARD TO ENGAGE. ON INSP, TURNED ON MASTER SWITCH AND ENGINE STARTED CRACKING. STARTER SOLENOID WAS STUCK ENGAGED. REPLACED STARTER SOLENOID P/N S1577-1. MASTER SOLENOID LOOKED BURNED, SO IT WAS REPLACED WITH P/N S1580-1. CHECKED BATTERY AND FOUND IT VERY LOW ON WATER, THE CASE WAS WARPED AND THE TERMINALS BLACK AND PARTIALLY MELTED. BELIEVE THE STARTER SOLENOID WAS ENGAGED IN-FLIGHT WHICH CAUSED THE BATTERY TO OVERHEAT. REPLACED BATTERY AND STARTER BENDIX. THE SOLENOIDS ARE LOCATED CLOSE TO THE RT MUFFLER WHICH SEEMS TO CAUSE EXCESSIVE HEAT ON THEM.
